PK.GM.2.3

PK.GM.2.3 Sort objects into sets by one or more attributes.

In a Nutshell

This objective asserts that the ability to identify similarities and differences is essential for students to be able to sort and group objects. Students will develop more complex ways to sort as they improve their ability to describe measurable attributes. By the end of Pre-K, students are expected to sort objects by one or more characteristics.

Student Actions	Teacher Actions
Build conceptual understanding by identifying one similarity of some of the objects and one difference such as color, size, or shape. Communicate mathematically by explaining how they sorted the objects, using mathematical vocabulary.	Establish mathematics goals by modeling how to find similarities and differences between two objects and by modeling sorting objects into two groups. Build procedural fluency and mathematical reasoning by providing opportunities for students to sort and explain how they sorted objects. Support productive struggle by asking students to sort in different and more complex ways.
Key Understandings	Misconceptions
Groups of objects can have similarities and differences. Sorting is putting things that are the same together.	Not applying the sorting rule consistently to the entire set.
